Invaders of Pluto, and Brain Stealers of Mars: Rich Horton on The Ultimate Weapon and The Planeteers by John W. Campbell

When I was twelve years old I read a book that changed my life. It was Before the Golden Age, a collection of Isaac Asimov’s favorite pulp tales from his own early teen years, and it inspired in me a love of the pulps that endures to this day.
One of the most captivating stories was John W. Campbell’s “The Brain Stealers of Mars,” from the December 1936 Thrilling Wonder Stories. The intrepid explorers Penton and Blake use an atomic-powered craft to visit Mars, where they find a sinister race of shapeshifters, eager to hitch a ride back to Earth. Sort of a prototype for “Who Goes There?”, the far more famous tale which Campbell published two years later in Astounding, “Brain Stealers” is more a science fiction puzzler than a true horror story, as our blaster-wielding heroes must find a way to outsmart an entire race of scheming telepathic shapeshifters with designs on conquest.
The Planeteers is a collection of five Penton & Blake tales published in Thrilling Wonder between 1936-38, following their adventures as they explore the solar system in their gleaming atomic spacecraft, discovering the double-minded aliens of Callisto, a benign race on Europa, and the super-intelligent energy eater out beyond Pluto. It appeared as half of an Ace Double in 1966, paired with The Ultimate Weapon, a standalone tale of the desperate race against time to create super-weapons on the Moon to thwart an alien invasion.
Rich Horton reviewed both books on his blog Strange at Ecbatan back in June. Here’s what he thought.
